Stack Monitoring for EBS

The Stack Monitoring service is a recent addition to the OCI Observability & Management family.

If you are running Oracle E-Business Suite (EBS) application today you will now be able to perform an auto discovery of all related resources in OCI Stack Monitoring. It will collect metrics specific for your EBS resources as well as ability to perform correlation across the EBS application and infrastructure stack as well as enable proactive alerting.

Components that will be auto discovered includes:

  • Concurrent Processing Node
  • Workflow Manager
  • WebLogic
  • Forms

Today, Stack Monitoring service supports EBS version 12.1 and 12.2 deployments hosted on OCI, On-Premise or Third Party Cloud (eg. AWS, Azure). 

In the example, I will show you how you can configure Stack Monitoring for EBS version 12.2.

Agents for Observability & Management

To use Observability & Management (O&M) services, there is the option to deploy OCI agents depending on which service you wish to enable.

There are two types of agents that can be used.

  1. Oracle Cloud Agent (OCA) – This agent is deployed by default if you provision hosts via the OCI Compute Service. OCA has extensions and plugins which can be used to enable other features native to OCI Compute Services.
  2. Management Agent (OMA) – This agent is a standalone version where you can deploy to hosts or VMs:
    – That do not have OCA installed on OCI eg. OCI Database Services (eg. Oracle Base VM/BM, ExaCS).
    – On-Premise
    – Third Party Cloud (AWS, Azure etc..)

Please see the current O&M support we have for each agent:

In previous post, I have provided steps on how you can install the Oracle Management Agent.

AWR Data Warehouse Repository using Autonomous Database

In Oracle Enterprise Manager (OEM) there is the ability to host an AWR Data Warehouse which enables you consolidate all your detailed performance data of all your database and store in a central location.

This enables you to do long-term analysis trend across your AWR data to determine, performance, capacity impact on the databases in your IT estate.

In OEM 13.5, Oracle now supports the AWR Warehouse repository for Autonomous Data Warehouse.

If you don’t have the infrastructure or capacity to store AWR data on-premise, you can now send your data to the Autonomous Data Warehouse (ADW) in Oracle Cloud (OCI).

There are enormous benefits to using Autonomous Data Warehouse (ADW). One of many benefits is that you can scale up/down cpu and storage whilst the database remains online.

Discover Autonomous Database in Enterprise Manager (EM)


In Enterprise Manager (EM) release 13.4 and 13.5, the Autonomous Database can be discovered as a target along with your other target databases on-premise deployments.

In this post I will share with you on how easily you can discover your Autonomous Database.

Monitoring External Oracle Database in OCI


The  OCI Observability & Management (O&M) platform gives you the ability to also manage your Oracle Database targets that reside on-premise or hosted on an external platform to OCI.

In order to deploy this, please ensure you have met the prerequisites:

  • Install the O&M Management Agent
  • Enable the Services for Agent Plugin :
    1. DB Management
      –  lifecycle database management capabilities for monitoring, performance management, tuning, and administration
    2. Operations Insights
      – analyze and forecast database performance and resource consumption

There are 2 Types of Deployments are available that can be Registered as External Databases

  • Option 1: Multitenant Architecture – Register Container Databases (CDB) and Pluggable Databases (PDB)
  • Option 2: Non-Multitenant Architecture – Register Non-Container Database (NCDB)

In this example we will show you how to register for:

Option 1: External Databases for the Multitenant Architecture.

Ingesting Logs into OCI Logging Analytics (via Agent Based Deployment)

Logs are often voluminous can be challenging to navigate through, but it can be a gold mine of valuable data to help administrators troubleshoot and identify issues or trends for operational activities.

To overcome the burden of manually eye-balling millions or (even billions) of rows in log records, bringing that data into OCI Logging Analytics (which is part of the Observability & Manageability Portfolio) will allow administrators to get quick insights, to reduce the time to isolate issues, minimising downtime and prevent impact to end users.

OCI Observability & Management Platform (O&M) – Agent Based Monitoring

There are various ways you can bring telemetry and operational data into OCI Observability & Management (O&M) to proactively monitor and gain operational insights into your IT fleet.

Example of ways you can do this are:

  • Service Connector Hub – Route and move data from one OCI service to Another OCI Service (eg. OCI Logging to Logging Analytics)
  • API Call – Collect data from files stored on Object Storage or Upload Log data on demand
  • Agent Based – Deployment of Agent on Host

If you have targets you want to monitor on-premise or in the cloud (OCI, AWS, Azure etc…) and you have access to the VM or Compute instance (ie. you can SSH or Remote Desktop to the host), then an Agent based method will allow you to collect and bring that data into unified platform in O&M.

In this example we will show how you can deploy Agent based method (on Linux OS) so you can leverage the O&M services including:

  • Logging Analytics
  • DB Management
  • Operations Insights
  • Java Management Service

1 – NETWORK COMMUNICATION (For External Targets to OCI)

NOTE: The additional network communication setup is not required if the targets you are monitoring are within your OCI tenancy account.

2 – ADDITIONAL PRE-REQUISITES

For Setup Compartments, IAM Groups and Policies

Please also check the following tasks has been completed.
https://docs.oracle.com/en-us/iaas/management-agents/doc/perform-prerequisites-deploying-management-agents.html

NOTE: You may need to contact your OCI administrator to grant you the appropriate permissions.

3 – DOWNLOAD AND CREATE KEY

  1. From OCI Console navigate to:

OBSERVABILITY & MANAGEMENT > MANAGEMENT AGENTS > DOWNLOADS AND KEYS > CREATE KEY

2. Specify details and Click on CREATE

  • Key Name (eg. oci-reg-key)
  • Compartment (eg. shared_resources)

3. Review Key and Download Key to File (eg. oci-reg-key.txt)

NOTE: Your Key File will be in the format of <Key Name>.txt. Copy it to your target host.

4. Download Agent by clicking on the Agent for your OS (eg. Agent for LINUX) and copy to your target host

Alternatively you can download the agent file using wget:
wget https://objectstorage.<oci-region>.oraclecloud.com/n/idtskf8cjzhp/b/installer/o/Linux-x86_64/latest/oracle.mgmt_agent.rpm 

Example:
wget https://objectstorage.ap-sydney-1.oraclecloud.com/n/idtskf8cjzhp/b/installer/o/Linux-x86_64/latest/oracle.mgmt_agent.rpm 

4 – INSTALL AGENT

1. Login to the host and locate the downloaded agent file oracle.mgmt_agent.rpm

$ sudo rpm -ivh oracle.mgmt_agent.rpm

Getting Insights with OCI Audit Log with Logging Analytics (via Service Connector)

Recently Clay Magouyrk, EVP of Oracle Cloud Infrastructure engineering announced the new Oracle Cloud Observability and Management Platform.

The new platform will provide OCI native integration to provide operational insights into our OCI services in addition to previous capabilities available in Oracle Management Cloud. Logging Analytics is the first major Oracle Management Cloud Service to be incorporated, and so my fellow colleague @callanhp and I were itching to give it a go and see how we could implement it, so we chose the most available logs we could think of, the audit logs from the OCI control plane.

In this blog we will discuss the mechanics for forwarding OCI Audit Logs to the Logging Analytics service from the Oracle Cloud Observability and Management platform, and discuss how this pattern can be extended to other log sources.

Let’s have a look at how you can do this.

This assumes you already have an EM deployment running.

The following is a summary of steps to enable EM reporting using Grafana:

1. Review the EM App for Grafana Certification
2. Install Grafana OS Package
3. Deploy EM App for Grafana Plugin
4. Configure EM for Grafana Settings
5. Enable Network Rules for Grafana Console
6. Configure Grafana Data Source
7. Access Dashboards
